BARRINGTON — The Planning Board is considering plans for a gravel pit in a residential area on Green Hill Road, next to the Rochester town line.

A public hearing on the project will take place on Tuesday.

According to Town Planner Marcia Gasses, while the area is zoned general residential, the town’s ordinance allows gravel pits to be built in that zone.

Residents who live close to the proposed excavation area have been raising concerns about potential noise levels, dust, truck traffic, and the site’s proximity to the Isinglass River, said Gasses.

She said the Rochester homes on Jessica Drive would generally be closer to the proposed 60-acre excavation site, while Barrington residents on Green Hill Road will witness heavier traffic.

At peak hour, trucks would be driving through Green Hill Road every 10 minutes, according to planning documents. It is estimated that at a maximum, trucks would make about 30 trips to the gravel pit per day.

Gasses said one issue with the truck traffic is that the base under Green Hill Road is not sufficient to handle truck traffic, and more base would need to be added if the project were given a green light.

The proposed excavation site would be about 1,800 feet from Green Hill Road, and more than 2,500 feet from Hansonville Road, according to planning documents.

Rochester’s Jessica Drive is about 200 feet north of the limits of the proposed excavation site.

“We have a number of concerned abutters in Rochester,” said Gasses.

In accordance to state law, the gravel pit will be at least 50 feet away from the property line of a neighbor who does not approve of the project. The pit also has to be at least 150 feet away from any dwelling unit, such as a home.

The excavation site will be at least 250 feet away from the Isinglass River.

The property of the proposed gravel pit is owned by Trinity Conservation LLC. Over the past 10 years, timber harvesting has been one of the uses for the site, according to Jason Hill, project manager at TFMoran engineering company.

According to a letter to the Planning Board submitted by Hill, Trinity Conservation would like to get an excavation permit for the site to provide construction aggregate to the community and throughout southern New Hampshire.

A conservation subdivision is planned for the property after the site is excavated for materials such as gravel and stone.

Gasses said that Rochester city officials, as well as Rochester residents, are expected to attend Tuesday’s public hearing, in addition to the affected residents in Barrington.

After the Planning Board accepts the project application as complete, the Strafford Regional Planning Commission will likely review the plans and their regional impact, said Gasses.

The project also requires an alteration of terrain permit, as well as a wetlands crossing permit from the state.

Tuesday’s public hearing will take place at 6:30 p.m., at the Early Childhood Learning Center on Ramsdell Lane.
